Specification of Letters Patent.

Application filed May 24, 1906. Serial No. 318,459. iMoclel.)

To all whom it may concern.-

Be it known that I, OVE L. GAMMELGAARD, a citizen of the United States, residint at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bracelets, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to bracelets, and is particularly adapted to that class of expansible bracelets comprising crossed arms working upon the lazy-tongs principle, of which the structure shown in United States Patent No. 782,188 is an example, which type is not adapted to receive an ornament or 0rnamental mounting intermediate its length, since to fix the free extremities of a pair of the centrally-pivoted arms would prevent any expansion of the adjacent bracelet parts. My mvention, however, is not limited to any particular form of bracelet, .its object being to join the bracelet-circlet to an ornamental setting intermediate its length without the use of solder, whose employment in this art has the well-known disadvantage of annealing the metal adjacent the soldered joint.

A further object is to provide a novel solderless means of mounting a removable ornament in the setting. Finally, it is purposed to so mount a setting or ornament in a lazytongs bracelet as to permit not only longitudinal or expansive movement of the bracelet from the ornament, but a transverse or rocking movement of the bracelet-bodyin relation thereto.

To the above ends, essentially, my inven-.

tion consists in the novel construction hereinafter described, and illustrated in the accompanying drawings, wherei11 Figure -1 is a front elevation of a bracelet of the lazy-tongs type embodying my inventtion; Fig. 2, a rear elevation of the section of the bracelet adjacent the ornament; Figs. 3 and 4, plan and transverse sectional vlews,

of the pivoted link with shell removed; Figs.

5 and 6, front and transverse sectional views, respectively, of an inner link-shell; Fig. 7, a front elevation of an outer link-shell; Fig. 8, a section of the ornament on line 1 1 of Fig. 2; Figs. 9 and 10, a plan and transverse section of one of the pivot-plates; Figs. 11 and 12,

l similar views of the pivot-plate covering; Fig. 13, a side elevation of the ring member; Fig. 14., a section on line 2 2 of Fig. 1; and Fig. 15, a fragmentary view of the bracelet, show- .ing the bracelet-body tilted in relation to the ornament.

Like reference-letters indicate like parts throu houtthe views.

In the embodiment of my invention herein shown, A represents a lazy-tongs braceletbody, comprising the series of arms a, centrally pivoted to the series of arms 7), an d the series of intermediate spring-cases c. D is an ornamental member which may or may not embrace a stone or gem. In the structure shown this member comprises a circular wall 6, provided upon its upper retracted portion with an inturned flange d and upon its lower margin with an inturned flange (1 the former to embrace a stone or gem E and the latter to retain the margins of a bearing-plate F for the gem, and a uard-plate G outside the bearing-plate. T e setting-wall (Z is provided with a series of openings h, preferably three, at diametrically opposite oints in each side of the wall. The setting 5 is provided with thin lateral extensions or plates I, (shown in detail in Fig. 9,) provided with lateral lugs i and a central opening '3. The lugs i are inserted through. the openings 71 of the setting-wall d and are riveted or swaged therein. Over each plate I is swaged an ornamental shell J, such as shown in Fig. 11, provided with a recess j, positioned to register with the opening i of the plate I. Pivoted to the plates 1, on each side thereof, are links K, each compr1sing an inner plat-e is with end perforations k 7., over one side of which is swaged an ornamental shell\7 A pivot-pin or rivet L, as shown in Fig. 14:, passes through the openings *P, j, and 15 thereby pivoting the links Kat their inner ends to the plates I. The outer ends of the links K are pivoted by rivets passing through the openings k to the ends of the adjacent arms a.

It will be noted that the shells J and k entirely conceal the rivet-heads and present fine-metal exterior. The parts are united without solder, and not only is longitudinal expansion of the bracelet aiforded, but a transverse swing thereof is permitted in relation to the ornament, as shown in Fig. 15.

When. a stone is not used in the ornamental body D, the bearing-plate F is omitted.

What I claim is 1. The combination with the crossed arms and settingmember of a lazy-tongs bracelet, of lateral plates upon the setting member, and links pivoted to the plates and tot-he adjacent crossed arms.

2. The combination with the crossed arms and setting member of a lazy-tongs bracelet, of lateral plates upon the setting member, and a air of links pivoted at their inner ends upon t ve opposite sides of each plate and pivotally connected at their outer ends with the adjacent crossed arms.

' 3. The combination with the crossed arms and setting member of a lazy-tongs bracelet, of pivotal means connecting the setting memher and crossed arms for permitting an inclination of the crossed arms in relation to the setting member.

4. An ornamental .unit for bracelets, the same comprising a circular wall provided with openings in its side, a flange upon its bottom, a guard-plate engaged by the flange and plate provided with 111 s'ada ted to enter the openings in the circu ar Wall.

5. An ornamental unit for bracelets the same comprising a circular wall provided with openings in its side a flange upon its bottom a flange upon its top a guard-plate engaged by the bottom flange, an ornament engaged by the upper flange and plates provided with lugs adapted to enter the openings in the circular wall.

n testimony whereof I have aflixed my signature in presence of two witnesses.
